Later, the skin turns violet, often with the development of large fluid-filled blisters (bullae). The fluid from these blisters is brown, watery, and sometimes foul smelling.

The gas creates bubbles under the skin and sometimes in the blisters themselves, causing the skin to feel crackly when pressed.
